I do one in cardboard to try to 'optimize' layout (never knowing what will
really be
optimum) then I do one in thin aluminum, to get all of the holes where I want
them.
I try to visualize and then mount all of the 'little stuff' like screws that
will hold the
bias board, and RF connectors for the relays, etc. I REALLY DON'T WANT to have
to tear into the 80% built final version to drill a little hole.
Due to my inability to engineer the whole thing properly from beginning to end,
I
sometimes end up with 'one way' construction. That is to say I install a thing
which
prevents access to an underlying thing, which covers another layer of... you
get the
idea.
To me a fairly complete mechanical mock-up (with no electricity ever applied,
except
maybe to the fan, to make sure the airflow is appropriate) is a very helpful
thing. If
you're more clever than I, your mileage may vary considerably.
